,To all whom t may concern: Fig. 5 is, a vertical section of the reetliliV of the occupants of the car, the robes, etc.,

Be it known that I, Grmnnns W.' BAnNErr, a. citizen `of the UnitedStates, residing at Phoenix, in the count;r of Maricopa and is such thatthere is less buck pressure on heat is evenly distributed and theclothing will not be burned by coming in Contact with the heating'casings.

It has for e. further object to provide a.

' heating system by which the lfront of the car can be heated withoutheating-fthe back ofV the' car, or vice v'erszi, `or both back and frontof the cer heated at the saine timeA -With complete control of the heatat al -I utilize all or part 'ofthe exhaust gases from the motor in thefront or beck heet ing 'chambers or cesings seperately or both at theseme time and provide neens to protect the occupants of the car from theextremel.;r heated surfaces;

Other objects und advantages ofA the invention will hereinafter appearnd the novel features thereof l.will be prticularly pointed out in theappended claims.

The invention is clearly illustrated inthe accompanyingdrewings, which,with the numerals of reference mnrlnedthereon, form y nlertnof thisspecication, and in which-v -lilfinvention, applied -as in Fig. 1.

i same is true .of the manner of holding the member 50 just described.

62 is a spring connected at one Aend to the other end of the arm 58 andlits other end connected in any suitable manner to some fixed part, as,for instance, the fioor of the` car or any convenient part. These bailieplates acting simultaneously and in unison control the intake and outletof heated gases from the engine to and from the heating casing 18, aswill be readily understoodupon reference to Fig. 2. The baiiie plate 38controls the intake to the heater casing 30.

It is evident that theasbestos lining to the casings may be held inposition in any suitable manner, by screws or the like.v The tops of theheater casin s may be Secured in position in any Well-gnomi Way, eitherfrictionally or by positive means, as may be found most ex dient, Y

It will beevldent .that the sprin s 52 and 62 serve to normally closethe ba e plates upon which they a'ct and also that the spring 47 servesto normally keep the valve 42 of the cut-out in its closed position.

The balieplates 38, 39 and 40 ma be to any desired angle so as to havecomp ete control .of the amount of heat admitted to the front heatercasing, as wel-l as that which shallpass to the control box, and alsothe heatI that` passes to the control box from the front casing can beutilized in the back casing. When the baie plate 40 is open, at anyangle to admit heat tothe front heater casing, the baflie plate 39 fromthe front heater casing to the control box is actuated by the segmentalgears and swung to a correspondin angle to admit the exL haust heat fromt e front heater casing to thecontrol box. Now, supposing that we getenough heat in the front heater casing with the balie'plates 39 and 40swung at an angle of 45 in the cpntrol box, part of th heat passes tothebaie plate 38 which is box, which d-iverts the heated gases that maypass the bae plates, .and also what,

heated gases pass downthrough the pipe 22 from-the front heater casingis all utilized` in the back heater casing. Now, should We lhave too4much heat in the back heater casing, the baiile plate 38 is raised,closing-the opening into the pipe 32, or set at any angle 4desired todivert. just what heat is needed,

letting part of the heat pass out'through the pipe'8 to the mumer 9.

Itis well-known that there ismore hea required in the back casing thanin the front casing .because the front of the car is more or less heatedfrom radiated heat from the engine. VIf no4 heat ,is required in thefront heater casing andV is required in the/back heater casing, the'baffle plates 39 and 40 are swungup against the top of the control box,closing the pi'pes 20 and 21 and the y baile plate 38 is swung to thedesired angleto divert the `required `heat through the plpe.

When the heated gases are diverted through the heater casings andexhausted through pipe 35 te the open air, the heating system acts as amuffler, and by means of t e cut-out valve 42 we have a direct cut-outto the open air near the engine, the same being' lcontrolled by themechanical means above described disposed within convenient' reach ofthe operator. The muiiler does not Aconstitute a part of the heatingsystem and when' the heating, system is employed it acts as a muierandthere is less backpressure on the engine than when ,gases are runningthrough-the ordinary muflier as there' are ,more expanding chambersin'.the heating system t an in most muiilers..The reticulated covers tothe casngsV ofthe heating aoc casings serve to protect the garments ofthe occupants of the car, as Well as the robes and the like, and insummer time they can be covered by a carpet or rug.

Importance is `attached to the asbestos'- lined casings which fromcooling the heating'casings,lthus.in.

prevent the cold 4air shoes, rubbers, dresses, etc; Also by thearrangement of the heating casings Within the asbestos-lined casings-With air spaces all around I get the direct benefit of'allradiated`heat from all surfaces up into .the'ean Importance is also attached tothe fact-that by my present construction I ,may admit y heat to thefront casing alone, tothe rear casing alone, or both simultaneously, orcan- .shut them both olf so that no heat passes 'to either,y the heatedgases passing directly throu h the muilier.
